Installation guide

Updating CPU/Memory PROM Code
B-4 Fault Tolerant System Administration (R1004H) HP-UX version 11.00.03
For more information about PROM-code file naming conventions, see
Table B-1.
4. When the prompt returns, switch the status of both CPU boards (that is,
activate the standby CPU board and put the active CPU board on standby) by
entering
ftsmaint switch hw_path
hw_path is the path of the CPU board to be brought online. For example, to
bring CPU board 0/1 online (and CPU board 0/0 offline), you would enter
the command
ftsmaint switch 0/1
This step can take up to five minutes to complete; however, the prompt will
return immediately.
5. Periodically check the status of the CPU board being taken offline by entering
ftsmaint ls hw_path | grep Status
hw_path is the hardware path of the CPU board for which you are checking
the status. For example, to check the status of CPU board 0/0. you would enter
the command
ftsmaint ls 0/0 | grep Status
6. When the Status changes from Online Standby Duplexing to Offline
Standby, update the CPU/memory PROM code of the board in the CPU
board now on standby by entering
ftsmaint burnprom -f prom_code hw_path
prom_code is the PROM code file in the CPU board, hw_path. For example,
to update CPU/memory PROM code in CPU board 0/0, you would enter the
command
ftsmaint burnprom -f G2X20fw7.0.bin 0/0
7. Duplex the CPU boards by entering
ftsmaint sync hw_path
hw_path is the hardware path of the CPU board you just updated. For example,
to duplex CPU board 0/0, you would enter the command
ftsmaint sync 0/0
NOTE
This step can take up to 15 minutes to complete; however, the prompt
returns immediately.
